What does a six-dimensional figure look like? Theoretical physicist Richard Nally can’t show you exactly, but he does have a sculpture – a pink shape the size of a grapefruit – that can help you imagi...
Two pillar theories in physics – general relativity and quantum mechanics – stand up well on their own, but are incompatible with each other.
Evidence disproving tropical ‘thermostat’ theory:global warming can breach limits for life
disproving tropical thermostat theory global warming breach limits for life
